I indeed hadn't thought about that.

I'm not the best person to weigh in on org details, but in general, it
looks good to me.

Just to confirm, then, this would allow me to specify:

1. oc-csl as default
2. oc-biblatex as default for latex
3. locally override

With 3, if on a particular document I didn't want 2, I'd just do this
in the document, which would suppress 2 in effect?

#+cite_export: csl style

...?

Would you have this nil by default, or is there a reasonable default
you could set?
